Embodiment
Below, embodiments of the present invention are described.
(the first execution mode)
Use Fig. 1, the battery system in the first execution mode is described.Fig. 1 is the figure of the structure representing battery system.
Battery system shown in Fig. 1 is equipped on vehicle.As vehicle, there are hybrid vehicle or electric automobile.Hybrid vehicle is except battery pack, also possess the vehicle as the power source for making vehicle travel such as fuel cell or internal combustion engine.Electric automobile only possesses the vehicle of battery pack as the power source of vehicle.
Battery pack 10 has the multiple monocells 11 be in series electrically connected.The quantity forming the monocell 11 of battery pack 10 suitably can set based on the requirement output of battery pack 10 etc.Battery pack 10 also can comprise the multiple monocells 11 be electrically connected in parallel.As monocell 11, Ni-MH battery or this kind of secondary cell of lithium ion battery can be used.
When using lithium ion battery as monocell 11, positive pole is formed by the material that can adsorb and release lithium ion, as this material, such as, can use cobalt acid lithium or LiMn2O4.Negative pole is formed by the material that can adsorb and release lithium ion, as this material, such as, can use carbon.When charging to monocell 11, positive pole releases lithium ion in electrolyte, the lithium ion in negative pole absorption electrolyte.In addition, when discharging to monocell 11, the lithium ion in positive pole absorption electrolyte, negative pole releases lithium ion in electrolyte.
Battery pack 10 is connected with booster circuit 22 via system main relay 21a, 21b, and booster circuit 22 makes the output voltage of battery pack 10 boost.Booster circuit 22 is connected with inverter 23, and the direct current power from booster circuit 22 is converted to alternating electromotive force by inverter 23.Motor generator (alternating current motor) 24 accepts the alternating electromotive force from inverter 23, thus generates the kinetic energy for making vehicle travel.The kinetic energy generated by motor generator 24 is passed to wheel.
Booster circuit 22 can omit.In addition, when using DC motor as motor generator 24, inverter 23 can be omitted.
When making vehicle deceleration or when stopping, the kinetic energy produced during the braking of motor generator 24 by vehicle is converted to electric energy.The alternating electromotive force generated by motor generator 24 is converted to direct current power by inverter 23.Booster circuit 22 supplies to battery pack 10 after making the output voltage step-down of inverter 23.Thereby, it is possible to regenerated electric power is stored in battery pack 10.
The electric current that current sensor 25 flows to battery pack 10 when detecting the discharge and recharge of battery pack 10, and export testing result to controller 30.Temperature sensor 26 detects the temperature of battery pack 10, and exports testing result to controller 30.The quantity of temperature sensor 26 can suitably set.When using multiple temperature sensor 26, the temperature of mean value as battery pack 10 of the temperature detected by multiple temperature sensor 26 can be used, or use the temperature that detected by specific temperature sensor 26 as the temperature of battery pack 10.
Voltage sensor 27 detects the voltage of battery pack 10, and exports testing result to controller 30.In the present embodiment, detect the voltage of battery pack 10, but be not limited thereto.Such as, the voltage of the monocell 11 forming battery pack 10 can be detected.In addition, the multiple monocells 11 forming battery pack 10 can be divided into multiple pieces, detect the voltage of each piece.Each piece at least comprises two monocells 11.
The action of controller 30 couples of system main relay 21a, 21b, booster circuit 22 and inverter 23 controls.Controller 30 has the memory 31 storing various information.In the present embodiment, controller 30 is built-in with memory 31, but memory 31 can be arranged on the outside of controller 30.
When the ignition switch of vehicle switches to connection from disconnection, system main relay 21a, 21b are switched to connection from disconnection by controller 30, or make booster circuit 22 and inverter 23 action.In addition, when ignition switch switches to disconnection from connection, system main relay 21a, 21b are switched to disconnection from connection by controller 30, or the action of booster circuit 22 and inverter 23 is stopped.
Then, use the flow chart shown in Fig. 2 and Fig. 3, the process controlled the discharge and recharge of battery pack 10 is described.Process shown in Fig. 2 and Fig. 3 was carried out repeatedly with the time interval preset (circulation timei).The program that the CPU execute store 31 that process shown in Fig. 2 and Fig. 3 is comprised by controller 30 stores and carrying out.
In step S101, controller 30 obtains discharge current value based on the output signal of current sensor 25.When battery pack 10 is discharged, discharge current value become on the occasion of, when charging to battery pack 10, discharge current value becomes negative value.
In step s 102, controller 30, based on the discharge current value obtained in step S101, calculates the SOC (StateOfCharge) of battery pack 10.Specifically, controller 30 adds up current value when carrying out the discharge and recharge of battery pack 10, thus can calculate the SOC of battery pack 10.In addition, the computational methods of SOC are not limited to method illustrated in the present embodiment, can suitably select known method.
In step s 103, controller 30, based on the output signal of temperature sensor 26, obtains the temperature of battery pack 10.In step S104, controller 30 calculates forgetting factor based on the SOC calculated in step s 102 and the temperature of battery pack 10 that obtains in step s 103.Forgetting factor is the coefficient corresponding with the diffusion velocity of the lithium ion in the electrolyte of monocell 11.Forgetting factor sets in the scope of condition meeting following formula (1).
O＜A×ΔT＜1···(1)
At this, A represents forgetting factor, and Δ T represents the circulation timei during process repeatedly carried out shown in Fig. 2 and Fig. 3.
Such as, controller 30 can use the mapping shown in Fig. 4 to determine forgetting factor.In the diagram, the longitudinal axis is forgetting factor, and transverse axis is the temperature of battery pack 10.Mapping shown in Fig. 4 can wait by experiment and obtain in advance, and can be stored in memory 31.In the mapping shown in Fig. 4, the diffusion velocity of lithium ion is faster, and forgetting factor is larger.Specifically, if the temperature of battery pack 10 is identical, then the SOC of battery pack 10 is higher, and forgetting factor is larger.In addition, if the SOC of battery pack 10 is identical, then the temperature of battery pack 10 is higher, and forgetting factor is larger.
In step S105, controller 30 calculates the reduction D (-) of evaluation of estimate.Evaluation of estimate D (N) is the value of the ageing state (high magnification described later is aging) evaluating battery pack 10 (monocell 11).
When carrying out the high-multiplying power discharge of monocell 11 constantly, the internal resistance of monocell 11 sometimes increases, and the output voltage producing monocell 11 starts the phenomenon that sharply declines.When this phenomenon occurs constantly, sometimes cause monocell 11 aging.What caused by high-multiplying power discharge is agingly called high magnification aging (being equivalent to the first degradation component).As the main cause that high magnification is aging, consider and carry out high-multiplying power discharge constantly, thus the ion concentration in the electrolyte of monocell 11 produces deviation.
Once it is aging that high magnification occurs, even if make discharge current value reduce or charge, the output voltage of monocell 11 sometimes also cannot be recovered.Therefore, need to suppress high-multiplying power discharge before the aging generation of high magnification.Therefore, in the present embodiment, evaluation of estimate D (N) is set as evaluating the aging value of high magnification.Computational methods about evaluation of estimate D (N) carry out describing later.
The reduction D (-) of evaluation of estimate according to from when calculating evaluation of estimate D (N) of last time (recently) to during through a circulation timei, the minimizing of the deviation of the lithium concentration of the diffusion of adjoint lithium ion and calculating.Such as, controller 30 can calculate the reduction D (-) of evaluation of estimate based on following formula (2).
D(-)＝A×ΔT×D(N-1)···(2)
At this, A and Δ T is identical with formula (1).D (N-1) represents the evaluation of estimate that last time, (recently) calculated.D (0) as initial value such as can be set to 0.
Shown in (1), " A × Δ T " value is the value from 0 to 1.Therefore, " A × Δ T " value is more close to 1, and the reduction D (-) of evaluation of estimate is larger.In other words, forgetting factor is larger, or circulation timei is longer, and the reduction D (-) of evaluation of estimate is larger.In addition, the computational methods of reduction D (-) are not limited to method illustrated in the present embodiment, can determine the minimizing of the deviation of lithium concentration.
In step s 106, controller 30 reads the current coefficient being pre-stored within memory 31.In step s 107, controller 30 calculates limiting value based on the SOC of the battery pack 10 calculated in step s 102 and the temperature of battery pack 10 that obtains in step s 103.
Such as, controller 30 can use the mapping shown in Fig. 5 to calculate limiting value.Mapping shown in Fig. 5 can wait by experiment and obtain in advance, and can be stored in memory 31.In Figure 5, the longitudinal axis is limiting value, and transverse axis is the temperature of battery pack 10.In the mapping shown in Fig. 5, if the temperature of battery pack 10 is identical, then the SOC of battery pack 10 is higher, and limiting value is larger.In addition, if the SOC of battery pack 10 is identical, then the temperature of battery pack 10 is higher, and limiting value is larger.
In step S108, controller 30 calculates the recruitment D (+) of evaluation of estimate.The recruitment D (+) of evaluation of estimate according to from when calculating evaluation of estimate D (N-1) of last time (recently) to during through a circulation timei, the increase of the deviation of the adjoint lithium concentration discharged and calculating.Such as, controller 30 can calculate the recruitment D (+) of evaluation of estimate based on following formula (3).
D(+)＝B/C×I×ΔT···(3)
At this, B represents current coefficient, is used in the value obtained in the process of step S106.C represents limiting value.I represents discharge current value, is used in the value detected in step S101.Δ T is identical with formula (1).
As from formula (3), discharge current value is larger, or circulation timei is longer, and the recruitment D (+) of evaluation of estimate is larger.In addition, the computational methods of recruitment D (+) are not limited to computational methods illustrated in the present embodiment.
In step S109, controller 30 calculates the evaluation of estimate D (N) in this circulation timei.This evaluation of estimate D (N) can calculate based on following formula (4).
D(N)＝D(N-1)-D(-)+D(+)···(4)
At this, D (N) is the evaluation of estimate in this circulation timei, and D (N-1) is the evaluation of estimate in the circulation timei of last time (recently).D (0) as initial value such as can be set as 0.D (-) and D (+) represents reduction and the recruitment of evaluation of estimate D, is used in the value calculated in step S105, S108.
In the present embodiment, shown in (4), can consider that the minimizing of the increase of the deviation of lithium concentration and the deviation of lithium concentration is to calculate evaluation of estimate D (N).Thus, the change (increase and decrease) of the deviation of the lithium concentration thinking the main cause that high magnification is aging can be made suitably to be reflected in evaluation of estimate D (N).Therefore, can the state of battery pack 10 be grasped based on evaluation of estimate D (N) and the degree of closeness of the aging state of high magnification occur.
In step s 110, controller 30 differentiates whether the evaluation of estimate D (N) calculated in step S109 exceedes the desired value preset.Desired value is set smaller than the aging value starting the evaluation of estimate D (N) occurred of high magnification.If evaluation of estimate D (N) exceedes desired value, enter step S111, otherwise enter step S117.
In the present embodiment, as shown in Figure 6, in the positive side and minus side of evaluation of estimate D (N), desired value is set with.Fig. 6 is the sequential chart of the change (example) representing evaluation of estimate D (N).The desired value of positive side and minus side is identical value as absolute value.In step s 110, when positive evaluation of estimate D (N) exceedes positive desired value and when negative evaluation of estimate D (N) exceedes negative desired value, step S111 is entered.That is, step S111 is entered when the absolute value of evaluation of estimate D (N) exceedes the absolute value of desired value.
In step S111, controller 30 carries out the accumulative of evaluation of estimate D (N).Specifically, as shown in Figure 6, when evaluation of estimate D (N) exceedes desired value, the part exceeding desired value in evaluation of estimate D (N) is added up.Accumulative process is carried out when evaluation of estimate D (N) exceedes desired value.
When positive evaluation of estimate D (N) exceedes the desired value of positive side, add the part exceeding desired value in evaluation of estimate D (N).On the other hand, when negative evaluation of estimate D (N) exceedes the desired value of minus side, the part exceeding desired value in evaluation of estimate D (N) is deducted.
In the present embodiment, when negative evaluation of estimate D (N) exceedes the desired value of minus side, deduct the part exceeding desired value in evaluation of estimate D (N), but be not limited thereto.Specifically, the accumulative process of evaluation of estimate only can be carried out when positive evaluation of estimate D (N) exceedes the desired value of positive side.In this case, when evaluation of estimate D (N) exceedes desired value, add the part exceeding desired value in evaluation of estimate D (N).
In the present embodiment, accumulative process is carried out for the part exceeding desired value in evaluation of estimate D (N), but is not limited thereto.Specifically, also this evaluation of estimate D (N) can be added up when evaluation of estimate D (N) exceedes desired value.In this case, consider desired value and change the threshold value described later.
In step S112, whether the aggregate-value Σ D (N) of controller 30 judgement and evaluation value is greater than threshold value.Threshold value is the value for allowing high magnification aging.In step S112, enter step S113 when aggregate-value Σ D (N) is less than threshold value, otherwise enter step S114.
Threshold value is not fixed value, according to the ageing state of battery pack 10 (monocell 11), being changed by the method that uses in other words according to battery pack 10.About the method for decision threshold, Fig. 7 is used to be described.
In step s 201, controller 30 obtain the temperature of the battery pack 10 when not carrying out discharge and recharge, the battery pack 10 when carrying out discharge and recharge temperature and carry out discharge and recharge time the turn on angle of battery pack 10.The situation of not carrying out the discharge and recharge of battery pack 10 refers to the situation of shelving the vehicle being equipped with battery pack 10.The temperature of battery pack 10 can obtain based on the output of temperature sensor 26.In addition, turn on angle can obtain based on the output of current sensor 25.
At this, in order to obtain the temperature of the battery pack 10 when not carrying out discharge and recharge, such as, the temperature sensor (different from temperature sensor 26) being pre-set at vehicle in order to detect outdoor temperature can be used.In addition, as the temperature of the battery pack 10 when not carrying out discharge and recharge, ignition switch also can be used just from the testing result disconnecting the temperature sensor 26 after switching to connection.
In step S202, controller 30, based on the information obtained in step s 201, determines the material aging of (presumption) battery pack 10 (monocell 11).Battery pack 10 (monocell 11) aging is divided into the aging and material aging of high magnification.Material aging (being equivalent to the second degradation component) refers to the aging of the material depending on monocell 11.In addition, degradation component when material aging is divided into the discharge and recharge not carrying out battery pack 10 (be called preserve aging) and degradation component when carrying out the discharge and recharge of battery pack 10 (be called be energized aging).
Preserve and agingly can the temperature of battery pack 10 based on the temperature of the battery pack 10 when not carrying out discharge and recharge, when in other words shelving vehicle to determine.If prepare the temperature of the battery pack 10 when discharge and recharge is not carried out in expression in advance and preserve the mapping of aging corresponding relation, then can determine to preserve aging.
Be energized and agingly can determine based on the temperature of the battery pack 10 when carrying out discharge and recharge and turn on angle.If prepare the mapping of the aging corresponding relation of the temperature of the battery pack 10 represented when carrying out discharge and recharge and turn on angle and energising in advance, then can determine that energising is aging.Preserve aging if can determine and be energized aging, then can determine material aging.
In step S203, controller 30, based on the material aging determined in step S202, determines the mapping that the high magnification of decision threshold is aging.As can be seen from figures 8 and 9, the mapping that high magnification is aging be represent threshold value, the mapping of the relation of the temperature (at this, being mean temperature) of battery pack 10 when carrying out discharge and recharge and the using state (Ah/km) of battery pack 10.The using state (Ah/km) of battery pack 10 is battery pack 10 discharge and recharges relative to the operating range of vehicle, can calculate based on the output of the output of operating range transducer and current sensor 25.
Mapping shown in Fig. 8 and Fig. 9 is the mutual asynchronous mapping of material aging.The material aging of answering with the mapping pair shown in Fig. 8 is greater than the material aging of answering with the mapping pair shown in Fig. 9.Battery pack 10 (monocell 11) aging be divided into material aging and high magnification aging, therefore material aging becomes large, then allow the aging ratio of high magnification to diminish, threshold value also diminishes.Threshold value shown in Fig. 8 is for being less than the value of the threshold value shown in Fig. 9.
Such as, it is aging to be difficult to generating material at low ambient temperatures, therefore can increase the ratio allowing high magnification aging.If prepare the mapping shown in multiple Fig. 8 and Fig. 9 according to the degree of material aging, then can determine the mapping corresponding with the material aging determined in step S202.
In step S204, the mapping that controller 30 is used in the high magnification determined in step S203 aging carrys out definite threshold.Specifically, controller 30 obtains the temperature of battery pack 10 and the using state (Ah/km) of battery pack 10, determines the threshold value corresponding with the temperature of battery pack 10 and using state (Ah/km).This threshold value uses in the process of the step S112 of Fig. 3.
In step S113, the export-restriction value being used for the charge and discharge control of battery pack 10 is set as maximum by controller 30.Export-restriction value is the value of the electric discharge for limiting battery pack 10, and the electric discharge of controller 30 pairs of battery pack 10 controls to avoid the output of battery pack 10 to exceed export-restriction value.
In step S114, export-restriction value is set smaller than the value of maximum by controller 30.Controller 30 can set according to the difference of aggregate-value Σ D (N) and threshold value the amount that export-restriction value is reduced relative to maximum.Such as, controller 30 can calculate export-restriction value based on following formula (5).
Wout＝W(MAX)-L×(ΣD(N)-K)···(5)
At this, Wout represents the export-restriction value for control of discharge, and W (MAX) represents the maximum of export-restriction value.L represents coefficient.K represents threshold value illustrated in step S112.
" L × (Σ D (N)-K) " value represents the amount that export-restriction value is reduced, and by making coefficient L change, thus can adjust reduction.Specifically, can consider that the cornering ability of vehicle is to adjust reduction.
In step sl 15, the instruction relevant with the control of discharge of battery pack 10 is sent to inverter 23 by controller 30.The information relevant with the export-restriction value set in step S113 or step S114 is comprised in this instruction.Thus, the electric discharge controlling battery pack 10 exceedes export-restriction value to avoid the discharged power of battery pack 10.
In step S116, this evaluation of estimate D (N) and aggregate-value Σ D (N) is stored in memory 31 by controller 30.Evaluation of estimate D (N) is stored in memory 31, thus the change of evaluation of estimate D (N) can be monitored.In addition, aggregate-value Σ D (N) is stored in memory 31, thus aggregate-value Σ D (N) can be upgraded when the evaluation of estimate D of next time (N+1) exceedes desired value.
On the other hand, in step s 110, enter step S117 when evaluation of estimate D (N) is less than desired value, in step S117, evaluation of estimate D (N) is stored in memory 31 by controller 30.Thereby, it is possible to the change of monitoring evaluation of estimate D (N).
According to the present embodiment, when aggregate-value Σ D (N) is greater than threshold value, the electric discharge of restriction battery pack 10 further, thus the battery pack 10 (monocell 11) that high-multiplying power discharge can be suppressed to cause is aging.In addition, to aggregate-value Σ D (N) arrives threshold value, export-restriction value keeps being set as maximum, therefore, it is possible to use the output of battery pack 10 to play the power performance of the vehicle that driver requires.
Figure 10 represents the aggregate-value Σ D (N) of change of adjoint evaluation of estimate D (N) and the sequential chart (example) of the change of export-restriction value.
Aggregate-value Σ D (N) is upgraded when evaluation of estimate D (N) exceedes desired value.And, at moment t1, when aggregate-value Σ D (N) arrives threshold value, change export-restriction value.Thus, the electric discharge of battery pack 10 is limited further.In addition, along with the difference expansion of aggregate-value Σ D (N) and threshold value, export-restriction value diminishes.On the other hand, to aggregate-value Σ D (N) arrives threshold value, export-restriction value is maintained maximum.
At moment t2, aggregate-value Σ D (N) is less than threshold value.Thus, export-restriction value is set as maximum.In time period before moment t2, along with close to moment t2, export-restriction value is close to maximum.During moment t2 to moment t3, export-restriction value is set as maximum.At moment t3, aggregate-value Σ D (N) exceedes threshold value, therefore changes export-restriction value.And according to the difference of aggregate-value Σ D (N) and threshold value, export-restriction value diminishes.
In the present embodiment, even if evaluation of estimate D (N) exceedes desired value, also do not change in this moment export-restriction value, and change export-restriction value when aggregate-value Σ D (N) arrives threshold value.By carrying out this control, even if after evaluation of estimate D (N) exceeding desired value, also can carry out the electric discharge of battery pack 10 on the basis that export-restriction value is maximum, and the power performance corresponding with the requirement of driver can be guaranteed.
In addition, according to the present embodiment, the material aging of presumption monocell 11, thus the scope that high magnification can be allowed aging can be determined.And, set the threshold value that the scope aging with allowing high magnification is corresponding, thus can allow to make battery pack 10 discharge in the aging scope of high magnification.If guarantee the electric discharge of battery pack 10, then can guarantee the power performance corresponding with the requirement of driver.
In the present embodiment, in each circulation timei, evaluation of estimate D (N) is stored in memory 31, and use the evaluation of estimate D (N-1) being stored in the last time (at once) of memory 31 to calculate this evaluation of estimate D (N), but be not limited thereto.Evaluation of estimate D (N) can be calculated based on the resume of discharge current value.Such as, only the resume of discharge current value can be stored in memory 31, the resume of use discharge current value calculate the evaluation of estimate D (N) in specific circulation timei.
In the present embodiment, the desired value used in the step S110 of Fig. 3 is set to the fixed value preset, but is not limited thereto.That is, desired value also can be made to change.Specifically, identical with present embodiment, presumption material aging determines the scope that high magnification can be allowed aging.And, when the aging scope of high magnification can be allowed to be less than reference range, the value of the desired value corresponding with reference range can be set smaller than.Set if so, then can increase the evaluation of estimate D (N) for the calculating of aggregate-value Σ D (N).On the other hand, when the aging scope of high magnification can be allowed to be greater than reference range, the value of the desired value corresponding with reference range can be set greater than.Set if so, then can reduce the evaluation of estimate D (N) for the calculating of aggregate-value Σ D (N).
